25
Q

the source of radiation (x-ray tube) is within the x-ray table

A

fluoroscopy

26
Q

helps in potentially decreasing the size of neoplasms

A

radiation therapy

27
Q

advantages for using x-ray

A

fast
useful treatment
easy diagnosis

28
Q

most procedures involved with x-ray are usually fast to process medical images (advantage for using x-ray)

A

fast

29
Q

for radiation therapy, it is helpful in reducing neoplasms to the patient. (advantage for using x-ray)

A

useful treatment

30
Q

can easily detect fractures, dislocations, soft tissue differences, air differences, air disturbances, and foreign objects (advantage for using x-rays)

A

easy diagnosis

31
Q

disadvantage x-rays

A

certain or random effects to cells
most body parts are radiosensitivie
ionizing radiation

32
Q

varying from the dose received can produce effects such as formation of hydrogen peroxide and cell alterations. (disadvantage x-rays)

A

certain or random effects to cells

33
Q

blood, dna, bone marrow, and gonads are some of the few examples that are radiosensitive to radiation. disadvantage x-rays

A

most body parts are radiosensitive

34
Q

very specific organs that are radiosensitive

A

thyroids (within the neck)
spleen (left side of our abdomen)

35
Q

is is typically harmful to the human tissue. (disadvantage x-rays)

A

ionizing radiation

36
Q

why are these non-ionizing radiation used>

A

non-ionizing radiation can be useful for reduced effects to the human body.

37
Q

why are ionizing radiation used

A

some radiation like positron and gamma rays are helpful in evaluating a person’s body fucntion

38
Q

is non-ionizing radiation safe than x-rays

A

non ionizing is less harmful but not safe. the common example of this is sunburn. meanwhile, ionizing is equally harmful

39
Q

sonography

A

sono - sound
graphy - getting an image

40
Q

usually for upper body diagnosis and soft tissue, mass, and lith diagnosis

A

ultrasound (sonography)

41
Q

lith

A

stone

42
Q

common stones being dianosed in humans

A

gallstones, kidney stones, urinary bladdre stones, and stones from the urethra and ureter

43
Q

we can also evaluate fractures here even though it is not a good perception or interpretation of bones

A

ultrasound

44
Q

usually for head/skull, blood vessel, and soft tissue/muscle diagnosis.

A

magnetic resonance imaging (mri)

45
Q

common injury in sports

A

muscle tears

46
Q

it looks like a long narrow tube that has both ends open. you lie down on a movable table that slides into the opening of the tube. a technologist monitors you from another room

A

mri machine

47
Q

creates a magnetic field around you, and radio waves are directed at your body. the procedure is painless. you don’t feel the magnetic field or radio waves, and there are no moving parts around you

A

mri machines

48
Q

for stroke

A

mri or ct scan

49
Q

for strokes, if it is an emergency what is recommended

A

ct scan

50
Q

used for body function diagnosis. radioactive drugs are injected to the patient

A

nuclear medicine

51
Q

some radiation therapy uses certain particulate and gamma radiation by injecting the material to the patient.

A

radiation therapy
